An explosion at an Encana Corp. natural gas well east of U.S. 85 between Platteville and Fort Lupton killed one man and injured three other workers just before 1 p.m. Wednesday.

Weld County Sheriff’s spokesman Tim Schwartz said the explosion appears to have been related to a pressure issue at the well. “Whatever machinery they were working on, that well head exploded.”

Schwartz said deputies on the scene saw no fire. “There was no fire to put out. Nothing was scorched.”

A Flight for Life helicopter responded to the Davis well pad near the intersection of Weld County Roads 22 and 31. Medical crews performed CPR on the 60-year-old victim but he could not be revived, Schwartz said.

A deputy leaving the scene of the accident Wednesday afternoon said the dead man was from Wyoming. He said two of the workers with minor injuries were taken for treatment in private vehicles.

Those people were treated at a hospital and released, company spokeswoman Wendy Wiedenbeck said.

An ambulance took the third person to North Colorado Medical Center in Greeley for treatment Wednesday, she said.

The dead man and the two workers who had minor injuries were employed by a company contracted to Encana. The worker who is hospitalized is an Encana employee.

Encana is investigating the accident, she said.

Schwartz said he expects the accident will be investigated by the Occupational Safety and Health Administration.

Details of the accident are unclear, but Encana spokesman Doug Hock said a new well was being drilled and a high pressure release of gas occured during the process of completing that work.

The pad is used for directional drilling for oil and gas, Wiedenbeck said.
